There are a number of cost-effective solutions to the problem of carbon-emissions. Here are two, which could be done in a short time-frame:

1. Switch to electric vehicles.

With the battery-switching system developed by Tesla Motors, infrastructure could be quickly and inexpensively built to enable all land-based vehicles (including 18-wheelers), to run exclusively on electricity.

If necessary, government could offer subsidies to help people purchase electric vehicles.

2. Replace coal and natural gas with nuclear.

I realize nuclear has its own problems, but it produces the smallest amount of Co2, which is, of course, the main priority.

With these two simple measures, both of which are technologically and financially achievable (and would create many new jobs), oil, coal and natural gas would be effectively eliminated as commonly used sources of energy.
